如何移动小平面标签(A,B,C)以使它们位于左上角的框内?
示例数据集:
date <- as.factor(rep(c(1,2,3,4,5,6,7,8), 7))
chlconc <- runif(56, min = 0.1, max = 15.9)
colony <- as.factor(c(rep("A", 24), rep("B", 16), rep("C", 16)))
year <- as.factor(c(rep("2014", 8), rep("2016", 8), rep("2017", 8), rep("2016", 8), rep("2017", 8), rep("2014", 8), rep("2017", 8)))
graphvalues <- data.frame(year, date, colony, chlconc)
ggplot代码
library(ggplot2)
library(ggthemes)
pd <- position_dodge(0.1)
ggplot(graphvalues, aes(date, chlconc, group = year)) +
facet_wrap(~colony, ncol = 1, labeller = label_parsed) +
geom_line(aes(color = year), position = pd) +
geom_point(aes(color = year), position = pd) +
scale_y_continuous(limit=c(0, 16), breaks=c(0, 4, 8, 12, 16), labels=c(0, 4, 8, 12, 16)) +
scale_color_discrete(name="Year") +
geom_hline(yintercept=2, linetype="dashed") +
theme(legend.text=element_text(size=14)) +
theme(axis.text=element_text(size=14)) +
theme(axis.title=element_text(size=18)) +
theme(legend.title=element_text(size=14)) +
theme_few() +
theme(strip.text = element_text(hjust = 0, size = 14, face = "bold"))
答案 0 :(得分:2)
Facet标签生活在情节区域之外,我不认为有办法让它们进入你的情节。但是,您可以在绘图区域内添加标签,方法是添加geom_text()
图层作为标签,并设置geom_text()
图层的x和y值,将其置于您的左上方图形。然后你也删除了facet标签。
ggplot(graphvalues, aes(date, chlconc, group = year)) +
facet_wrap(~colony, ncol = 1) +
geom_line(aes(color = year), position = pd) +
geom_point(aes(color = year), position = pd) +
scale_y_continuous(limit=c(0, 16), breaks=c(0, 4, 8, 12, 16), labels=c(0, 4, 8, 12, 16)) +
scale_color_discrete(name="Year") +
geom_hline(yintercept=2, linetype="dashed") +
theme_classic() +
theme(strip.text = element_blank(), #remove strip text
strip.background = element_blank()) + #remove strip rectangles
geom_text(aes(label = colony, x = 0.75, y = 15.5)) #add titles using geom_text()
